Abstract
The collecting chamber connects to the ground (b) of the wedge-shaped groove. In an apparatus for diverting of a liquid from a capillary (7;12;14) in a collecting chamber, has wedge-shaped grooves (1;13;17) in a body on the outlet of the capillary which graduates into a capillary; a curved radius (r) of wedge-edge of the groove which is as small as the half of the smallest measurement of the largest capillary which graduates in a wedge-shaped groove; and has a wedge angle (alpha) between the wedge surface of the groove next to the wedge edge which is smaller than 150 degrees.
